Title: Unmanned carrier
Inventor: INUI KENZO
IPC: G05D1/02
Filed: 1992-01-23
Abstract: PURPOSE:To make it possible to detect an obstacle in a vertical up-and-down direction by a simple constitution by connecting plural obstacle detecting bar with a rotary shaft and detecting the amount moved by the detecting bar in contact with the obstacle as the rotational amount of the rotary shaft. CONSTITUTION:When an obstacle is brought into contact with either one of plural provided obstacle detecting bars 8 while an unmanned carrier 1 runs on a prescribed running route, the detecting bar 8 is made to move in the opposite direction to the running direction of the unmanned carrier 1 by the contact. At this time, a poll 5 rotates with the shaft as a center by being pulled by the motion of the detecting bar 8 and a limit switch 7 becomes an ON state. By this ON signal of this limit switch, the operation of the unmanned carrier is stopped or the unmanned carrier is made to perform the operation of the obstacle evasion. Thus, the collision between the obstacle, the unmanned carrier and the cargo can be prevented.

Title: Solar heat collector
Inventor: MORI SHIYUNICHIROU
IPC: F24S90/00
Filed: 1982-01-26
Abstract: PURPOSE:To make it possible to collect heat at the time when the sun shines intermittently and  to increase the heat collecting efficiency of the solar heat collector by a method wherein a  pump adopted to circulate a heat transfer medium forcibly between a collector section and a  heat exchage section of a heat accumulation tank is provided and a flow passage switching  device capable of allowing the heat transfer medium to flow near the inlet-outlet port of the  heat exchange section by bypassing the heat exchange section. CONSTITUTION:When heat transfer medium is heated by the collector section 2 of a heat collector 1 due to intermittent insolation and the difference between the temperature of the heat  transfer medium and the temperature of a heat accumulating medium near the heat exchange  section 7 of a heat accumulation tank 6 reaches a predetermined value, a differential thermostat A (not snown) responds thereto to thereby operate a pump 9. As a result, the heated heat transfer medium is transferred near the flow passage switching device 11 through a pipe 3  whereupon a differential thermostat B (not shown) responds thereto so that the flow passage  switching device 11 operates to flow the heat transfer medium to the heat exchange section 7.  At the initial stage of circulation of the heat transfer medium, the flow passage switching device 11 makes the heat transfer medium bypass the heat exchange section 7 while the heat  transfer medium is cool so that the heat accumulating medium is not deprived of its heat by  the heat transfer medium but the device 11 allows the heat transfer medium to flow into the  heat exchange section 7 when the heat transfer medium is in a heated condition. Accordingly,  the heat transfer medium performs only the function of promoting the heat accumulating action  of the heat accumulating medium in the heat accumulation tank 6.

Title: Head-unlatching control method for hard disk drive
Inventor: RI CHUKO
IPC: G11B21/12
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To provide a head-unlatching control method in which the head speed in the unlatching operation is stabilized so as to prevent an error and in which the succeeding operation is controlled favorably by a method wherein the unlatching current is regulated on the basis of the result of the computation/of the head speed by making use of servo information which is read out from the head during the execution of the unlatching operation. SOLUTION: A servo synchronizing operation and a speed check are executed in an acceleration period and a deceleration period. When either the head speed > the speed limit value or the unlatching deceleration current > the minimum value which can not perform the servo synchronizing operation, the unlatching deceleration current is decreased stepwise by Δbrake, e.g. 12mA, a head deceleration operation is performed slowly, and a deceleration control operation is continued. When the above three conditions are all satisfied, the unlatching current is set forcedly to '0'. The head speed can be expressed by ΔTrack/T (where T represents the sampling cycle, and ΔTrack represents the distance between the previous track and the present there).

Filed: 1982-01-29
Abstract: PURPOSE:To subject molten metal to preliminary refining such as desiliconization, and dephosphorization without eroding a lance by blowing refining agents through the lance provided above the molten iron flowing in a molten iron spout. CONSTITUTION:In the stage of subjecting molten iron to preliminary refining such as desiliconization and dephosphorization, desiliconizing agents and dephosphorizing agents in a tank 5 are blown through a lance 4 disposed above the molten metal flow 2 into the molten iron flowing in a tapping spout 1 by means of gaseous substances for conveying such as N2, Ar, CO2, air, steam or O2. Since the lance 4 is not immersed into the flow 2, there is no erosion of the lance by the molten iron, and since there is a large clearance between the preceding end of the lance 4 and the bottom part of the spout 1, the erosion in the bottom part of the spout 1 owing to the preliminary refining agents does not arise and the lance is usable with a long serivce life.

Title: Rotor head for distributor
Inventor: OMORI MASAO
IPC: F02P7/02
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To reduce stress produced in a resin part by centrifugal whirling and the like due to the unbalance of a rotor head so as to enhance reliability, by embedding into a resin the tip of the electrode side of a collar to receive a screw for integrally attaching a shaft and the rotor head. SOLUTION: In a distributor, when an ignition signal from a control unit is inputted to an ignitor unit 16, the ignitor unit 16 disconnects the primary side of an ignition coil 17, and generates high voltage on the secondary side of the ignition coil 17. This high voltage is transmitted to the electrode 25 of a rotor head 24 through a spring 22 and a carbon brush 23, and next discharged to the side electrode 29 of a cap 20. The rotor head 24 is fitted to the tip of a shaft by a collar 27, and fixed by a screw 28. In this case, the collar 27 is embedded into a resin part 26 so that a torque produced due to the rotational fluctuation of the collar 27 is shared to the circumference of the collar 27, therefore, stress caused in the resin is diminished.
